Build.Observe.

I'm Johnny Hu. I build AI products, from metered model calls to jobs that recover when they fail.

The other half is photography: light, places and small things.

Enterprise AI application platform

Metered model calls.Recoverable AI jobs. Read the case study My part of a team build: usage metering and organisation quotas at the gateway, model pricing, and background jobs that retry only what failed. ≈80% fewer tokensSame job, measured in the test environment

J&S Photo Studio A culling tool built around my own photography workflow. Clinical ML Clinical machine learning, from the model through to deployment. Multimodal Research Research at King's College London: measurements, text and location, read together.
A wide city street seen against the light. The sun is a bright white disc in a blue sky between office buildings. In the foreground two people walk across the white stripes of a pedestrian crossing as dark silhouettes. Further back a man walks down the road, a scooter rider waits at the right edge, and cars line the avenue. : open it in Photography

A little more about me

About

I build enterprise AI products, focused on usage, cost and reliability.

I'm part of a team building an enterprise AI application platform. My part is where models meet real use: what a call costs, who may make it, and what happens when a long job fails halfway.

I trust behaviour I can reproduce. When a data split in my research leaked, I regrouped it and redrew the figures rather than keep numbers that looked better than they were.

Management and delivery

Outside work I photograph, on a Fujifilm, a Ricoh GR and the Dazz app. It keeps me looking at small things, which is most of engineering too.
